You mean the strips are demaminating ?
What you need to is open them up even more with a series of straight pins so that you can get as much glue in as possible
I'd use Gorilla Glue because it expands and will fill into areas that you couldn't reach with epoxy.
Then wrap the area with string to "clamp" it

Yes the strips are coming apart a little bit . So I wil get them glued up before replacing the tip. Thanks Joseph
